The theme is FA5-only, but aksrt_icon_markup() prefixed bare glyphs with
the FA4 style token, so stored icon-picker values rendered FA4 markup,
and three runtime strings still carried the FA4 double-fa form (report
modal header and submit button, comment report menu item). That left the
navigation icon contract failing at 11/12.
- aksrt_icon_markup() normalizes bare glyphs, legacy FA4 values and
style-only values to "fa fas fa-<glyph>", keeping the FA5 brand family
(fa fab) and trailing classes intact.
- aksrt_normalize_icon_key() strips the legacy FA4 prefix so stored
values resolve against the brand-icon catalog again.
- report.js and the comment report item emit FA5 markup.
- An icon-picker contract test locks the upgrade behaviour.
Verification: 338 widget-system, 12 navigation, 28 admin and 13
front-submit contract tests pass; normalization also exercised against
legacy, FA5 and brand inputs.
